Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 4LFF is a 1U rack-mount server designed for organisations that need dense compute in a standard rack. It ships with one Intel Xeon Silver 4210 processor running at 2.2 GHz with ten cores and 128 GB of DDR4 ECC registered memory. A second processor socket is available for future expansion up to two CPUs.

PERC H740P RAID Controller and 10 GbE Networking

The integrated PERC H740P RAID controller manages up to four 3.5-inch SATA drive bays, providing hardware RAID levels for data protection and performance. A dual-port 10 GbE 562T adapter delivers high-throughput networking for virtualisation or storage traffic. Remote management is handled by iDRAC9 with an Enterprise licence for full out-of-band control.

Memory Scales to 7.68 TB with Four Drive Bays

The platform supports a maximum memory capacity of 7.68 TB across its DIMM slots, giving substantial headroom for memory-intensive workloads. Storage capacity is limited to the four 3.5-inch bays, so deployments requiring many drives will need external enclosures. Dual 750 W power supplies provide redundancy for the configured components.

Questions about this item

How often should the 750 W power supplies be checked or swapped in a 24/7 R640?

The two 750 W supplies are hot-pluggable; run them in redundant mode and replace a unit only when iDRAC9 reports a fault or the amber LED lights.

Which component limits sustained throughput first in this R640 with a Xeon Silver 4210?

The 10-core 2.2 GHz CPU saturates before the PERC H740P or the 128 GB DDR4 become bottlenecks.

How loud and hot does the 4-bay 3.5" chassis get under constant load?

Dual 750 W fans spin up to high RPM under full load; expect noticeable airflow noise and exhaust heat in a confined rack space.
